LUCET labs


developing state-of-the-art research-based assessment instruments




LUCET’s test development laboratory TD_Lab regroups the centre’s core methodological expertise. The TD_Lab primarily ensures the development of culture-fair large-scale competency tests for the Luxembourg school monitoring programme ÉpStan. Every ÉpStan competence test is typically developed by a working-group of content experts (i.e., practicing teachers) under the coordination and guidance of TD_Lab specialists. Crucially, the TD_Lab also explicitly serves as an internal peer review platform to assure and continuously develop the scientific quality of all LUCET assessment instruments. Notably, the LUCET TD_Lab is consulted on a regular basis for University internal and external assessment enterprises.

collecting and processing high-quality (large-scale) paper-based assessment data




LUCET’s optical mark and character recognition laboratory OMCR_Lab is the centre’s only non-virtual lab structure. Occupying about a quarter of the surface area in the basement of the University of Luxembourg’s Maison des Sciences Humaines, the OMCR_Lab is among the Faculty’s biggest and most secure research facilities. The impressive specifications of the OMCR_Lab include high-capacity printing and packing lines, industrial-grade cutting-machines, high-performance scanners, state-of-the-art design stations and ergonomically conceived workspaces for dozens of assistants. LUCET’s OMCR_Lab can be shared on request and depending on availability for University-of-Luxembourg-based research projects and surveys.

collecting and processing high-quality (large-scale) digital assessment data




LUCET’s computer-based testing laboratory CBT_Lab is the home and birthplace of the centre’s in-house online assessment system OASYS. The CBT_Lab administers LUCET’s server structure, and deploys the centre’s mobile testing units. All CBT_Lab products are planned, documented, developed and maintained according to high industry standards. Notably, whenever possible, CBT_Lab products are designed in close collaboration with the University’s Human-Computer Interaction (HCI) research group, thus ensuring optimized user experience. LUCET’s CBT_Lab products can be shared on request and depending on availability for University-of-Luxembourg-based research projects and surveys.

analysing and visualising (longitudinal) large-scale assessment data




LUCET’s large-scale statistics laboratory LSS_Lab regroups the centre’s expertise in advanced statistical methods. The LSS_Lab primarily ensures the state-of-the-art analysis and reporting of cross-sectional and longitudinal large-scale assessment data from LUCET’s commissioned research endeavours. Naturally, full GDPR compliance is imperative for all processing of personal data. Importantly, the LSS_Lab also hosts and administers LUCET’s unique longitudinal database emerging from the Luxembourg school monitoring programme ÉpStan. For the purpose of original research and high-impact scientific publications, LUCET researchers have privileged access to the aforementioned database—however, access is not limited to in-house scientists. Notably, the LUCET LSS_Lab’s data analytical expertise is consulted on a regular basis by University internal and external researchers.
